Replaces toxic and flammable solvents
SiOx CO2 machine technology replaces processes traditionally carried out in perchloroethylene, hydrocarbons and other toxic and/or flammable solvents. The working fluid is carbon dioxide (CO2) under pressure, environmentally friendly, non-toxic and cheap. We offer liquid CO2 technology which has all the advantages of supercritical CO2 – but at much lower investment costs.
SiOx machines AB provides the modern alternative to treatment of especially silicone rubber items in ovens or in extraction processes. We call it SiCure. Conventional processes consume a lot of electricity or use toxic / flammable solvents. Our method – SiCure – extracts silicone or extender oils using liquid carbon dioxide (LCO2).
KEY ADVANTAGES:
- Short process times
- Reduction of residues to 50 ppm of silicone oils
- No drying step necessary
- No re-polymerization effect
- No cut-healing due to re-polymerization.
Mechanical properties of silicone rubber are maintained, in some cases with a small effect on permanent deformation. No formation of SiO2 dust. Very low energy / electricity consumption compared to thermal curing. 99% CO2 recovery by distillation within the machine. No solvent and residue emissions to atmosphere and working environment.
The three basic processes
Our machines can do.
Cleaning
Extraction
Impregnation of water-soluble or non-water soluble materials
Flexible machine
Many possibilities
Our machines are very versatile due to the ”platform” or modular design, comprising a treatment vessel for the goods, a storage and a recovery system for CO2 and additives. With industry-specific modifications, the machines are employed in very diverse industries such as leather processing, metal treatment , modification of plastics and biopolymers, and many special tasks e.g. in the pharma industry.
The ”platform design” enables us to reduce construction and manufacturing costs – whilst keeping all the benefits of the advanced CO2 technology. We do not compromise when safety, quality and reliability is concerned.
